vtioned character wherein a manually actuated pump isassociated with the cover of the receptacle for creating a pressurel in the top of the receptacle for feeding the contents of the receptacle outwardly therefrom,

a gage being associated with the cover whereby the pressure in the receptacle may the same:

be readily ascertained.

A further object is to provide a douching apparatus of the4 above mentioned character, which is simple in construction, inexpensive, strong and durable and furthermore adapted for the purposes for which it is desig nated. A

ther objects and advantages of this invention will become apparent during'the course of the following description.

In the accompanyingdrawing forming a. part of this specification and in which like numerals designate like parts throughout Figure l is a side elevation, and Figure -2 is an enlarged vertical sectional view 'through the receptacle showing my invention associated with the cover thereof.'k

ln'the drawing wherein for the purpose of illustration is shown the preferred e1nbodiment of my invention, the numeral l designates a substantially cylindrical open top receptacle, the sanie being provided with anoutlet opening 2 adjacent the bottom thereof. y A cover 3 is provided for the open top of the receptacle and the same is normally held in a sealed position thereon by b inea-ns of the swing bail 4 which is pivotally supported at itsrespective ends at diametrically opposite points on the receptacle.

The intermediate portion of the bail is 'adapted for engagement with the locking cam 5 which extends upwardly from the central portion of the cover. A rubber sealing ius obviating the necessity Y whereby a pressure vserial ne. maia?.

ring\6 yis also carried bythe cover in theh manner more clearly illustrated in Figure 2 of the drawing.

A hand operated pump of any Well known construction is shown at 7 and the upper portion of the saine is externally threaded at 8 whereby the same is support-ed in a suitable internally threaded opening 9 provided 1n the cover 3. The handle '10 of the pump '1" is disposed above the cover 3 Wherebythe pump may be easily foradmitting compressed air to the interior of the upper portion of the receptacle l v will be applied to the liquid contents of the and efliciently actuated receptacle to lperiiiit l the same to 'How easily through the outlet 2 when the valve 11 1s open and through the discharge tube or hose 12. The air outlet of the pump 7 is shown at 13 and is sor arranged as tocause the air to be disdiarged from the pump un construction shown in Figure 2.

n air gage is associated with the cover 3 whereby the amount of air pressure within the receptacle he air y gage includes a diaphragm 14C which is supported aroundl the lower portion of the annular ing from the cover 3. A plunger 16 is asso* ciated with the diaphragm 14 and thevupper end of the plunger extends upwardly through a suitable opening provided in the cover 3 and into'a graduated glass tube 17 which is supported 'on the cover 3 by the fasL tening bolts 18, the heads of through a cap 19 provided for the upper portion of the glass tube. Acoil spring 20 encircles the plunger rod 16 and is disposed between the diaphragm and the cover as clearly illustrated in Figure 2.

While have shown the preferred embodiment of my invention, it is to he understood that various changes in they size, shape and arrangement of parts may be resorted to without departing from the spirit of the in claim.

Having thus described the invention, what 100- claim is In combination, a cover for a receptacle,

may be readily ascertained.

flange 15, the` latter dependwhich extend der compression into the top of the receptacle as is obvious from theA cover and provided with a head engageable with the diaphragm, a spring disposed about the rod and tensioned to hold said head in engagement with the diaphragm and to hold medew said diaphragm flexed outwardly of the annular flange, n transparent 'tube on the exterior of the cover for receiving the rod, and 10 means for holding said tube in place.

In testimony whereof I aix my signature.l
